Nuts 5 aisi 316 – code: a4-934-05 – Osculati

Osculati AISI 316 hex nut – size 5 (code a4-934-05)

The hex nut in AISI 316 stainless steel Osculati, size 5, Osculati code a4-934-05 (SKU: oscu000001395), is a small hardware component designed to complete and restore tightening on screws or studs in contexts where stainless steel material consistency is required. In nautical and onboard plant engineering, the choice of an AISI 316 nut is often linked to the need to maintain uniformity in bolting and simplify spare parts management, especially when working on existing installations.

This item belongs to the family of hexagonal nuts indicated as UNI 5588 / DIN 934 (manufacturer's reference), useful information for inclusion in the bill of materials, for scheduled maintenance, and for quick reordering by code.

Product features and details

Material: stainless steel AISI 316

The nut is made of AISI 316, , a common choice when you want to use stainless steel fasteners in technical applications. During maintenance or replacement, keeping the same material as the existing bolting helps preserve assembly consistency and reduce uncertainties in spare parts selection.

Format: hexagonal nut

The geometry hexagonal is the most widespread standard for assembly and disassembly operations with common tools. It is a practical solution for routine interventions, spot replacements, and tightening activities in accessible spaces.

Dimensional and regulatory references (as per manufacturer)

• Size: 5
• Family / reference: UNI 5588 / DIN 934

The reference to DIN 934 and UNI 5588 facilitates the identification of the nut type and alignment with components already on board or in the system. In professional contexts, this aspect is particularly useful to avoid ambiguities between similar items and to properly manage stocks and reorders.

Identification and traceability for reordering

• Supplier: Osculati S.r.l.
• Supplier product code: a4-934-05
• SKU: oscu000001395

The presence of clear codes allows speeding up procurement, especially when working with bills of materials, maintenance plans, or spare parts requests. In case of replacing existing fasteners, being able to quickly trace the code reduces downtime and simplifies communication between the technical office, warehouse, and installer.

Typical applications (nautical and plant engineering)

This hex nut is indicated as a fastening component for general uses where screws or studs compatible with the size are used 5. In nautical and plant engineering fields, it can be used in multiple points of the boat or system, for example during:

• Routine maintenance on assemblies with stainless steel bolting;
• Replacements of worn, missing, or no longer suitable nuts;
• Restorations of tightenings on brackets, supports, and service fasteners;
• Assemblies and small assemblies where you want to maintain material consistency in stainless steel.

In general, it is a useful item when you want to maintain uniformity in hardware and reduce the variety of materials used in the same fastening group.

Usage and operational notes

Check compatibility before assembly

Before installation, it is advisable to check the measurement and compatibility with the screw or stud on which it will be mounted, as well as correspondence with any standard required by the project or existing fasteners (reference DIN 934 / UNI 5588).

Good maintenance practices

• Visual inspection of the nut and the thread of the mated component before tightening.
• Replacement of the fasteners when damaged or no longer reliable for the intended use.
• Warehouse management through SKU and supplier code to reduce search and reorder times.

For specific applications or critical assemblies, it is good practice to follow internal procedures and the indications of the designer/installer, choosing fasteners based on the system's needs and operating conditions.
